Step 1 (band size), and step 2 (band size) correspond to the ratio of band sizes of step 1 regularisation (raw) and step 2: interpolation in relation to step 1: regularisation (interpolation), which can also be seen in Fig. 10. Steps difference is the difference between the two band sizes. In bold, key parameters shown in Fig. 12
